As shown in Figure 7, the sector gear 171 with circumference of about 1/4 is fixed on the base end part of head components M2 in an end one of its circumferencial direction.The turning axle 172 of sector gear 171 remains on first fixed mount 173.First fixed mount 173 constitutes the part of housing BD (apparatus main body M).Head components M2 is with respect to housing BD (apparatus main body M), is that the center opens and closes with the turning axle 172 of sector gear 171.
On first fixed mount 173, be formed with along the track segment 174 of the first positive dirction D11 and first negative direction D12 extension.On track segment 174, maintain tooth bar 175.Tooth bar 175 plays the effect that displacing force applies parts, and this displacing force applies parts and applies and be used to power that first moving-member 110 is moved to the first positive dirction D11.Tooth bar 175 links with sector gear 171 engagements by a pair of neutral gear 176.
In addition, as Fig. 8 and shown in Figure 9, first auxiliary section 113 is to giving prominence to and be arranged on first moving-member 110 with respect to the direction of the first positive dirction D11 and the first negative direction D12 quadrature.On the other hand, the side of tooth bar 175 is provided with second auxiliary section 177 that cooperates with first auxiliary section 113.First auxiliary section 113 and second auxiliary section 177 constitute, and when tooth bar 175 begins not cooperate when mobile, and are cooperating behind the mobile predetermined distance K on the first positive dirction D11 when tooth bar 175.
Because parts travel mechanism 100 possesses said structure, along with opening of head components M2, tooth bar 175 moves to the first positive dirction D11 along track segment 174 by sector gear 171 and a pair of neutral gear 176.And along with tooth bar 175 is moved further after the first positive dirction D11 moves predetermined distance K, first moving-member 110 in the parts travel mechanism 100 moves to the first positive dirction D11.
On the other hand, as shown in figure 10, second moving-member 120 forms long band plate-like, can move with respect to second fixed mount 181, and be supported by second fixed mount 181.Second fixed mount 181 constitutes the part of housing BD (apparatus main body M).Second fixed mount 181 extends along the second positive dirction D21 and the second negative direction D22 of second moving-member 120.Tensioning is provided with volute spring 182 between second fixed mount 181 and second moving-member 120, as the force application part that second moving-member 120 is applied acting force.Volute spring 182 allow along with first moving-member 110 to the moving of the first positive dirction D11, second moving-member 120 moves to the second positive dirction D21 by strip-shaped parts 130.And, along with second moving-member 120 to the moving of the second positive dirction D21, volute spring 182 produces and makes second moving-member 120 move the acting force of the direction of returning to the second negative direction D22.
As shown in Figure 10 and Figure 11, optical sensor 160 is installed as being cleaned parts on second fixed mount 181.Optical sensor 160 for example is the sensor of detected image concentration.Optical sensor 160 is fixed on second fixed mount 181 with the mode that window 161 is positioned at the upper surface of this optical sensor 160 with the light transmission that is made of transparent component.
Be formed with notch part 123 on second moving-member 120.Notch part 123 is formed, and is used for when second moving-member 120 is positioned at common origin position (reference position), when head components M2 closes, and can not block the light that penetrates with window 161 from the light transmission of optical sensor 160.Near the lower surface of second moving-member 120 this notch part 123 is equipped with the wiper 190 as cleaning member.
Because parts travel mechanism 100 possesses said structure, along with second moving-member 120 moving to the second positive dirction D21 and the second negative direction D22, wiper 190 with move back and forth when the light transmission of optical sensor 160 contacts with window 161, to carry out the cleaning of light transmission with window 161.
Next, by Figure 12 to Figure 15 illustrate present embodiment parts travel mechanism 100 action and by the relevant action of switching 100 associations of parts travel mechanism, head components M2 with the cleaning of being undertaken by wiper 190.
Figure 12 is the stereographic map of the head components M2 of expression in the printer 1 relevant action state of head components M2 and parts travel mechanism 100 when beginning to open.Figure 13 is the cross-sectional plan view of the head components M2 of expression in the printer 1 first moving-member 110 and major part of the association status of tooth bar 175 when beginning to open.Figure 14 is the stereographic map of the head components M2 of expression in the printer 1 relevant action state of head components M2 and parts travel mechanism 100 when being opened to maximum.Figure 15 is the cross-sectional plan view of the head components M2 of expression in the printer 1 first moving-member 110 and major part of the association status of tooth bar 175 when being opened to maximum.
When head components M2 closed as shown in Figure 7, as shown in Figure 9, first auxiliary section 113 of first moving-member 110 in the parts travel mechanism 100 was separated by predetermined distance K with second auxiliary section 177 of tooth bar 175 and separates, and is in not mated condition.
And at this moment, as shown in Figure 10 and Figure 11, second moving-member 120 in the parts travel mechanism 100 is owing to the acting force of volute spring 182 remains on the origin position (reference position).Thus, the notch part 123 of second moving-member 120 is relative with window 161 with the light transmission of optical sensor 160.Therefore, the light that penetrates with window 161 from light transmission normally carries out the image color detection for not being blocked by optical sensor 160.
Under this state, as shown in figure 12, when head components M2 is center when beginning to open with turning axle 172, sector gear 171 rotations.The revolving force of sector gear 171 is delivered to tooth bar 175 by a pair of neutral gear 176.Thus, tooth bar 175 beginnings are moved to the first positive dirction D11.Till the first positive dirction D11 moved to mobile predetermined distance K, as described in Figure 13, first auxiliary section 113 of first moving-member 110 edged down upon mutually with second auxiliary section 177 of tooth bar 175, is in not mated condition from tooth bar 175 beginnings.
When head components M2 approximately opens half, and tooth bar 175 is when moving predetermined distance K, matches with second auxiliary section 177 of tooth bar 175 in first auxiliary section 113 of first moving-member 110.

In addition, along with second moving-member 120 to the moving of the second positive dirction D21, volute spring 182 tensionings also are stretched.Producing thus makes second moving-member 120 move the acting force that returns to the second negative direction D22 direction.
And when closing head components M2, by sector gear 171 and a pair of neutral gear 176, tooth bar 175 moves to the first negative direction D12 and returns.Meanwhile, by the acting force that volute spring 182 is produced, second moving-member 120 moves to the second negative direction D22 and returns.
Along with this second moving-member 120 to moving that the second negative direction D22 returns, wiper 190 moves to equidirectional (the second negative direction D22), and contact with window 161 with the light transmission of optical sensor 160, with clear light once more through usefulness window 161.
And, along with second moving-member 120 to moving that the second negative direction D22 returns, also move (returning) by strip-shaped parts 130, the first moving-members 110 to the first negative direction D12.Thus, as shown in Figure 9, first auxiliary section 113 of first moving-member 110 is separated from each other with second auxiliary section 177 of tooth bar 175 and returns to not mated condition.Therefore, by set the cooperation position of first auxiliary section 113 and second auxiliary section 177 according to the size of tooth bar 175 amount of movements,, the amount of movement of first moving-member 110 can be set arbitrarily also even under the bigger situation of the amount of movement of tooth bar 175.
So, parts travel mechanism 100 according to present embodiment, by strip-shaped parts 130 conduct connection first moving-members 110 of use bendability excellence and the parts of second moving-member 120, can avoid various driver elements or portion of mechanism easily, improve the degree of freedom that is provided with of strip-shaped parts 130.In addition, because the bending direction of strip-shaped parts 130 is easy to determine, thereby when assembling parts travel mechanism 100, strip-shaped parts 130 is set easily.
